Please find the token workflow in the following. Signature: created by signing (encoded header + encoded payload) using a secret key. Payload: encoded data of claims intended to share. Header: encoded data of token type and the algorithm used to sign the data. JWT consists of the following three parts: A JWT helps the resource server verify the token data using the same secret key, so that you can trust the data. It is open standard and defines a better way for transferring data securely between two entities (client and server).Ī JWT is digitally signed using a secret key by a token provider or authentication server.

Note: In this demo application, I have used ASP.NET Core 3.1, Entity Framework Core 3.1 with Visual Studio 2019 16.4.0, SQL Server 2017, and Postman. Create database and connect it to application.Create an ASP.NET Core REST API application.I am going to develop a sample application for an inventory REST service with basic operations. In this blog, I am going to provide a walkthrough on developing REST APIs using ASP.NET Core 3.1, connecting with existing databases using Entity Framework, creating a JWT token, and securing APIs.
